WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 225,577, dated March16, 1880.

Application filed July 21, 1879.

To all whom it may concern:

Be it known that I, DANIEL DRAWBAUGH, of Eberlys Mills, in the county ofCumberland and State of Pennsylvania, have invented an Improvement inWater-Wheels, which improvement is fully set forth in the followingspecification, reference being had to the ac companying drawings.

The object of my invention is to provide a water Wheel or motor of suchnature and construction that the full force of the water admittedthereon from a hydrant, main, or other body of water having pressure maybe utilized by directing the current, by a graduated approach, all theway around onto the periphery of wheel, which is provided with transverse paddles or blades, and at the base of each of said bladesdeflectors to catch the current by action and reaction, and yet allow itperspective, parts of said wheel and the shaft.

on which it is mounted, and other parts of my device. Fig. 3 is asectional view of the wheel case, showing the interior thereof, and thewheel in perspective. Fig. 4 represents my wheel-hub. Fig. 5 represents,in perspective, my water-wheel gate, and in section, also, the packingdevices on the stem thereof. Fig. 6 is a perspective of one of mywheel-bucket structures, composed of upright blade, de flectors, andattaching-foot.

I construct my improved wheel with a hub, S, having centrally thereonthe disk Q, deeply notched at points at, and mounted on the shaft Mcentrally in an ellipsoidal cavity, m m, in a vertically two-partedcase, K A B, the ellipsoid being divided through the major axis. On.said hub S Q are attached such parts as are shown in Fig. 6, in positionas shown in Figs. 2 and 3, by screws or rivets at points 01 p, the foot6 being set in a notch, :10, and the deflectors or buckets n being ofsuch conformation, as shown, so as to fill the equal subdivisions of thecircle, the blades Q projecting into the space S S of case. (Shown inFig. 3.) Said deflectors n are arranged in pairs in front of the bladesQ, as shown in Fig. 6, and are obliquely directed to shed the Wateraside from the middle of the wheel, while driv- 6o ing it by directimpact of current as well as by reaction through the current, beingdeflected on its way to be discharged at the passages. m m, as will behereinafter more fully set forth.

The case by which my improved wheel is inclosed and mounted is composedof two nearly equal sections, similar in general features, (denoted byletters A (l W K V and A G W K P.) The base of each is a flange, W 0,through which, by bolts or rivets a, the sections are held united, awire, H, inlaid on their matched faces, serving to guide them upon eachother and to make the joint watertight. Each of said sections has thescrewthreaded extension It, over which a joint-connector, L, is passedto attach the inlet-pipe L, and each has also the screw-threadedextension K, over which is attached the exitpipe N. Each of saidsections has the swell or raised part A, to give such enlargement as thecavity m m requires, whereat each of said sections is recessed insemi-ellipsoidal form. One of said sections has formed on it the closedbox 1?, in which is the bearing for end T of wheel-shaft M which has itsbearing in the opposite section in the ring E, and the packing g,pressed by said ring when forced in by the capped nut W, applied overthe packing-box V, formed as a part of said section of wheel-case.

Each section has in it the exit-passage m, separated from theinlet-channel at S by the double casing at O, as shown in Fig. 2; andeach section of said case has inlet R, converg- 5 inginward to the gateH which is inserted in a cylindrical transverse cavity, snugly fillingit by its body. Said gate is cut away at G to afford full inlet-passagewhen it is turned, as shown in Figs. 3 and 2.

When the handle B, attached to stem H of said gate, is turned as shownin Fig. 1, the inlet-passage is closed by said part G being revolved tostand across it, and at all intermediate points between a full-closedand a full-open gate the stream is directed by said part G to rush alongthe outer wall of the channel or curb S, that it may not be counteractedby itself, but pass on around the wheel, as is hereinafter fully setforth. Said gate H G H is held in its socket by the ring J and packingh, compressed by the screwcap nut N, applied over neck V, formed on oneof said case-sections, as shown in Figs. 1 and 5. A stop, Z, on handle Bof said gate limits its throw both when open and when closed.

The channel S S is the passage by which the water is admitted onto mywheel. Said channel is of uniform breadth, one-half thereof being ineach section of case, as shown in Fig. 2, and the wheel paddles orblades Q snugly fill the cross-section of said channel, but not itsdepth, except at its extreme limit between S and S the floor or outercurb of said channel being a spiral, and being more remote from saidblades at S than at succeed ing intermediate points in its circuit, andits approach being gradual, as shown in Fig.3, its inner margin being acircle.

The object of constructing the outer curb of said channel so as to havea winding approach to the said wheel is, that the water may glide aroundthe wheel and engage it at all points in such manner that the action onthe wheel may produce balanced pressure upon its bearings and thedistribution of the current so as to have a portion thereof let ontoeach of the wheel-blades Q and the deflectors n n thereat. The wholemomentum of the stream admitted under pressure may be realized both bydirect action of the swirling stream in said channel, and also by thereaction while being deflected to the exit-passages m m after concussionon the blades Q.

Moreover, when gate H is turned to let onto the wheel less than fullfeed, the admitted stream will pass the blades at S, and those to therear of it, freely, and will swirl on in said channel S S over the wheelto the more confined part of said channel, where, by having its pathclosed by the wheel-blades Q, concentrated plunging occurs, and thewheel is propelled thereby, both by velocity of current and by themomentum from reaction.

The driving-power is, however, not fully obtained to propel my motor,especially when it is run rapidly, unless the vacuum produced about thecenter of the wheel is relieved by a vent to admit air into the spacedenoted by letter m, as otherwise the discharge through the spaces mwill be retarded by atmospheric pressure at the discharge-orifice tofill said vacuum, thus producing a gurgling flow of the issuing stream.Such vent is located at Z, Figs. 1 and 2, vertically above box P andclose to it, into which aperture a bent tube may be inserted with itsfree end directed vertically. Said vent is most efficient if directlyopposite in direction to the discharge-orifice. If said aperture l is,however, unprovided with said bent tube, the water will not escapethereat from the wheel-case, as there is, on the contrary, a keencurrent of air rushing into the case at said vent hole, which operatesto quicken the flow of the issuing stream of the used water; and itappears also to assist the propulsion of the wheel by a shifting of thelocation of the vacuum, so that it operates by forward suction ortraction upon the deflectors a, in effect like an additional stream letthereon.

The stream of air thus admitted not only perfects the discharge of theused water, but it becomes a positive working factor, and the power ofthe motor is much increased thereby.

Having sufflciently described my invention, what I regard as new anduseful, and what I desire to secure by Letters Patent of the UnitedStates, is substantially as follows:

1. A water-wheel having its periphery provided with radially projectingtransverse blades or paddles adapted to snugly ply in the channel of thecase, by which the stream is admitted onto the wheel, and having thesides of said blades provided with deflectors for shedding aside thestream after impact on said blades toward passages for discharging thewater from the case inclosing the wheel, substantially as and for thepurpose set forth.

2. The hydraulic motor-wheel casing constructed with the peculiarclearing-apartment of ellipsoidal form about the wheel-center, forshedding the used water properly to the exits therein, and of anadjoining scroll inlet-passage extending entirely around thewheelperiphery, to admit the stream thereon undividedly and with equalbearing on opposite sides thereof, in the manner and for the purpose setforth.
